I purchased my F75 about 3 weeks ago and just love it. I have learned a lot from all the good people in this forum. I have not seen a lot of posts though on what readings people are getting on bullets, buttons, shrapnel, etc. I made a relic garden with a 3-ring, a piece of shrapnel, and a button. The readings come in around "70" on the meter, but the confidence meter is extremely low. Would like to hear what other people are experiencing. Thanks,
